16. CPA Points and Alarms

CPA (Closest Point of Approach) points are shown for both own vessel and the detected vessels, when the alarm level for the object is either 'warning' or ‘danger’. For vessels that have the highest CPA “danger” state, "Collision Danger” alarm label will also be shown.

Inform=no circle, only gray lines, (CPA < 250m and TCPA < 5min)


Warning=pulsing yellow circle and dashed yellow line (CPA < 50m and TCPA < 3min)

Danger=pulsing red circle and dashed red line (CPA < 5m and TCPA < 1min)

A Course Over Ground dashed line for own vessel is shown when CPA points are enabled. Default dashed color is blue for Notify state, and the line is colored according to the highest warning alarm.



CPA Alarms and CPA Points features can be enabled from the radial menu.
